Abstract: Embodiments of the present invention provide a data processing device and a data processing method. In the data processing device and the data processing method provided by the embodiments of the present invention, first data in a memory is written into a first non-volatile storage unit in a log file form, and a log file of the first data written into the first non-volatile storage unit is written into a second non-volatile storage unit. Because a data write speed of the first non-volatile storage unit is higher than a data write speed of the second non-volatile storage unit, fast backup of the data in the memory can be achieved, and when the data in the memory is lost in an abnormal situation, security of the data in the memory can be ensured.

Abstract: A storage detection apparatus is placed in an operating system in kernel mode; after file information is intercepted and a security level of file content is determined, file content of a high security level is redirected to a storage area of high storage security; the security level of the file content itself is determined and stored, which is transparent to a user, thereby implementing division of security levels for different documents generated by a same application.
Abstract translation: 将存储检测装置置于内核模式的操作系统中; 在文件信息被拦截并且确定文件内容的安全级别之后，高安全级别的文件内容被重定向到高存储安全性的存储区域; 确定并存储对用户透明的文件内容本身的安全级别，从而实现由相同应用生成的不同文档的安全级别划分。

Abstract: A data copy management apparatus and a data copy method thereof. The data copy method includes obtaining, using a hash algorithm, hash values of multiple source data blocks obtained by dividing source data; sending the hash values to a target storage side, so that the target storage side determines, based on the received hash values, whether the target storage side directly generates the source data blocks or a source storage side sends the source data blocks to the target storage side; ignoring the source data blocks when a first feedback fed back by the target storage side is received; and sending the source data blocks to the target storage side when a second feedback fed back by the target storage side is received. Thus, a speed of copying a special data block can be improved, saving central processing (CPU) and network resources and reducing copy time.
Abstract translation: 数据复制管理装置及其数据复制方法。 数据复制方法包括：使用散列算法获得通过划分源数据获得的多个源数据块的散列值; 将哈希值发送到目标存储侧，使得目标存储侧基于接收到的散列值确定目标存储器是否直接生成源数据块，或者源存储器侧将源数据块发送到目标存储器 侧; 当接收到由目标存储侧反馈的第一反馈时，忽略源数据块; 以及当接收到由目标存储侧反馈的第二反馈时，将源数据块发送到目标存储侧。 因此，可以提高复制特殊数据块的速度，节省中央处理（CPU）和网络资源，缩短复制时间。
